A newbie here- about stopping a set Intevals

hello i’m new to flash ang hoping to create a flash interactive animation.

lately i’ve learned about set intervals.

i used it to create a simple animation where my object will fade in from 0% alpha to 70%. but i just don’t know how to do it. ive browsed around your forum but as of now in my present skill in AS. i can’t understand some of it. maybe some of you guys can help me.

here is my code.

function fader():Void {
mcBilog._alpha++;
updateAfterEvent;
}

mcBilog._alpha = 0;

var nAnimate:Number = setInterval (fader, 10);

hope to here from you.tnx
